Flush Transmission and Radiator?

I don't know if the quick oil change place's "machine" gets it all in one go, so it would be cheaper to get it done there if your trans oil is as horrible as that.

Thanks for the reminder. One more reason I may keep my truck forever. The torque converter has a drain plug. Drain the pan and TC and I get all but about 2 quarts out of the trans before I refill. I think 2001 or 2002 was the last year for this feature on Fords. Easy DIY.

Having the drain plug in the TC and pan are nice features, but the main advantage to dropping the pan is to see what shavings are inside the pan and wiping the sludge build up out. Also the magnet inside the pan needs to be cleaned because it can only hold so many magnetic particles. As I said in my first reply the remainder of the fluid can be pumped out using the transmission pump by just disconnecting the trans line to radiator as running the engine until the fluid comes out clean while you add new fluid. I would defiantly drop the pan for at least the first fluid change and the second depending on what it looks like inside.
